STMicroelectronics L6743B High Current MOSFET Driver Datasheet

About this manual

The L6743B is a flexible, high-frequency dual-driver specifically designed to drive N-channel MOSFETs connected in a synchronous-rectified buck topology. It embeds high-current drivers for both high-side and low-side MOSFETs and accepts a flexible power supply between 5 V and 12 V to optimize gate-drive voltage. The device includes an integrated bootstrap diode and adaptive dead-time management to minimize shoot-through and body diode conduction time.
